<p>I've wondered about this for a while. There is a need to map
these features both within large gardens (particularly those which
are tourist attractions), parkland, campus locations and even
typical townscapes.</p>
<p>For reference I wrote about botantical gardens some time ago: <a

</p>
<p>My working notes on which features may need to be mapped are <a
moz-do-not-send="true"
href="https://wiki.openstreetmap.org/wiki/User:SK53/Garden">here</a>
. Please note that although I use the key garden (by analogy to
things like golf), I am aware that this probably clashes far too
much with existing usage, and that another key will be needed.</p>
<p>I'm currently looking fairly intensively at these features in my
local university campus. Looking for something else I came across
detailed plans for planting of areas associated with new buildings
including lists of plants and layout by the landscape designer. My
starting point was to check my identifications of <a
moz-do-not-send="true"
href="https://twitter.com/SK53onOSM/status/1222163049798361088/photo/2">plants</a>,
but of course I now have a good place to try out any tagging
scheme.</p>
<p>The main components are:</p>
<ul>
<li>Regular beds, often alongside a path of building. Some are
planted with perennial herbs, but many are planted with shrubs,
and increasinly ornamental grasses are used.<br>
</li>
<li>Areas of wild flowers. These are predominantly native wild
flowers, introduced in a special turf (£20 sq m) rather than the
mixes which are commonly described as wild flower which are
usually colourful annuals from North America. These areas are
only cut once a year.</li>
<li>Numerous lawns, amenity grassland and a playing field
(recreation ground area)</li>
<li>Many low hedges planted with Yew (so-called "instant hedge"
ordered by the metre), various cultivars of Cherry Laurel,
various Berberis species, Box-leaved Honeysuckle, Christmas Box.
Some of these grade into areas of shrubs.</li>
<li>A few taller hedges planted with a mix of native species
(Blackthorn, Hazel, Hawthorn, Rose).<br>
</li>
<li>Shrub areas including smallish trees (Magnolia, Wintersweet),
Bamboos, low-spreading Juniper and Spanish Gorse. More extensive
single species plantings of Cotoneaster, Hazel and various
Dogwoods Cornus.<br>
</li>
<li>A major tree avenue planted with Scholar's Tree (was Sophora
japonica but has changed it's name).</li>
<li>Numerous specimen trees & areas more densly planted with
trees to the point they can be mapped as woods</li>
<li>Some trees (not many) are planted in tree pits and the area of
the pit is covered with a non-climbing Ivy</li>
<li>Many smaller buildings have climbers planted at their foot
with a trellis attached to the building. In these cases the
associated bed is small.</li>
<li>Large specimen plants which are notionally herbs. Notably New
Zealand Flax Phormium and Pampas Grass Cortaderia selloana.</li>
<li>Wetland planting (Phragmites, Typha, Carex) now more or less
entirely naturalised and thus suitable for natural=wetland
tagging.</li>
<li>Planting interspersed with ornamental pebbles</li>
<li>A very small number of containers (planters) and raised beds</li>
<li>Limited areas of persistent tall herb vegetation (mainly close
to wetland features) something where I dont think we have a
commonly used natural tag.</li>
<li>Extensive areas around the fenced perimeter which have may be
from 1-5 m thick consisting of a mix of small trees, large
shrubs and other woody plants (Brambles, Honeysuckle, Agave).
This would originally have been a border planted at regular
intervals with shrubs (Cherrylaurel, Acuba, Forsythia, Elder)
which gradually became overgrown with self-sown plants
(Cherries, Sycamore, Birch, Bramble) and plants escaping from
adjoining gardens. At a stretch this could be described as
natural=scrub.</li>
</ul>
<p>Having written this list I obviously ought to turn it into a blog
post and illustrate each of these feature.</p>

<pre class="moz-quote-pre" wrap="">In the discussion about `barrier=hedge` areas, it is clear that
mappers want a way to tag small areas of bushes and shrubs, and not
everyone is happy about using natural=scrub for this case.
Currently there is a tag landuse=grass for small areas of managed
grass, but this might be considered to exclude other non-woody herbs.
And leisure=garden is usually considered the whole area of a garden,
rather than being limited to a certain type of vegetation.
I would suggest that we need a more developed system of tags for
micro-mapping small areas of plants, not just woody-stemmed bushes and
shrubs, but also semi-annuals, herbaceous perenials (e.g. in the
tropics) and annual flowers and herbs.
This would also help with problems like using village_green for all
sorts of areas: see discussions and examples in
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/Talk:Tag:landuse%3Dvillage_green">https://wiki.openstreetmap.org/wiki/Talk:Tag:landuse%3Dvillage_green</a>
Rather than just discussing how the tag small areas of bushes or
hedges, how about how to tag this area of flowers:
<a class="moz-txt-link-freetext" href="https://wiki.openstreetmap.org/wiki/File:Vg6.jpg">https://wiki.openstreetmap.org/wiki/File:Vg6.jpg</a>
Or a garden bed planted with these:
<a class="moz-txt-link-freetext" href="https://www.thaigardendesign.com/bird-of-paradise-strelitzia/">https://www.thaigardendesign.com/bird-of-paradise-strelitzia/</a> - or
these: <a class="moz-txt-link-freetext" href="https://www.wikilawn.com/flowers/ornamental-red-ginger-plant-alpinia-purpurata/">https://www.wikilawn.com/flowers/ornamental-red-ginger-plant-alpinia-purpurata/</a>
Or this bed full of succulent plants, in a semi-arid region:

Are people micro-mapping areas such as these?
How specific should the tagging be?
